What is AI application development?
AI application development builds software that uses artificial intelligence, such as large language models (LLMs) and machine learning, to answer questions, draft content, extract data from documents, make predictions or take actions. Common patterns include retrieval-augmented generation (RAG), which grounds answers in an organization's own documents, AI agents that call tools and APIs to complete tasks, and copilots embedded in existing applications. TechTiera builds AI applications with evaluation, security and human oversight designed in.

How TechTiera approaches AI application development
Getting AI from pilot to production
- Pick a narrow job with a measurable result, such as answering policy questions or extracting invoice fields.
- Prepare the data: clean, current content with permissions that carry into retrieval.
- Build an evaluation set of real questions and correct answers before choosing a model.
- Design guardrails: what the AI may and may not do, and when a person takes over.
- Monitor in production: accuracy, cost, latency and user feedback reviewed every release.
Why content expertise matters for AI
Most enterprise knowledge sits in document systems. TechTiera has long run content management practices for OpenText Documentum, Microsoft 365 and SharePoint, Alfresco and capture platforms, so AI assistants are built on well-structured, well-governed content rather than whatever can be scraped together.
Typical use cases
- Policy and knowledge assistants
- Contract and document review
- Customer service copilots
- Invoice and form extraction
- Sales and proposal drafting
- Engineering document search

AI Application Development FAQs
What is retrieval-augmented generation (RAG)?
RAG is a pattern in which an AI application first retrieves relevant passages from your own documents or data, then asks a language model to answer using only those passages, with citations. It reduces made-up answers and keeps responses current.
What is an AI agent?
An AI agent is software that uses a language model to plan steps and call tools or APIs to complete a task, such as looking up an order and issuing a refund, within limits you set.
How do you stop an AI application giving wrong answers?
By grounding it in trusted data, testing it against a set of real questions with known answers, adding guardrails and human review for risky actions, and monitoring accuracy after launch.
Is our data safe when we use generative AI?
It can be. TechTiera uses enterprise model services that do not train on your data, enforces your permissions at retrieval, and logs and reviews AI activity.
